length of snout, 4 in head, and 2 in width of interorbital space. Origin 

 of dorsal midway between tip of caudal and posterior margin of orbit, 

 over sixteenth scale of lateral line ; first anal ray under third of dorsal ; 

 dorsal and anal fins subquadrangular, of moderate height, the latter fin 

 being scarcely higher than long; caudal fin subtruncate. Brownish 

 above and on sides, each scale darker on tip ; an indistinct dark band 

 along middle of tail; firrs immaculate, anal with the lower margin whit- 

 ish. Guatemala. (Giinther.) (TTO^C, thick; K^aAr/, head.)

971. ADINIA DUGESII (Bean). 



Head 3 ; depth nearly 3 ; eye 4 in head, f width of interorbital space. 

 D. 15 ; A. 11 ; scales 30-11. Body short and deep, robust ; head depressed 

 above ; snout short, shorter than eye ; jaws short, the upper being freely 

 protractile. Teeth slender, conical, in a double series, those of the 

 outer enlarged. Opercle connected by membrane to the shoulder girdle, 

 beginning at a point in line of lower margin of eye. Anal very 

 short, its base half as long as dorsal base ; insertion of dorsal very slightly 

 in advance of anal at a distance from the front of the eye equaling about 

 twice the length of the head, its rays slender, not very long, the long- 

 est somewhat shorter than base of fin and less than half head ; base of 

 dorsal 2 in head; anal inserted under third ray of dorsal, its longest ray 

 i to f head ; anal base very short, % as long as the dorsal base, and very 

 little longer than the eye; pectoral half head; caudal slightly rounded; 

 ventral in middle of length of body, excluding caudal, its tip not reach- 

 ing vent, 36 in head. Light brown ; sides with 5 broad distinct bands 

 or 6 dusky bands, the widest somewhat greater than eye ; one of these 

 bands placed under anterior half of the dorsal ; sides and head with 

 silver. Length 3 inches. Guanajuato, Mexico. (Bean.) Evidently a 

 species of Adinia, as is shown by the form and by the restriction of 

 the gill openings. (Named for its discoverer, Prof. Alfredo Duges, of 

 Guanajuato.)

972. ADINIA MULTIFASCIATA,* Girard. 



Head 3 ; depth 2 (2f to 2| in $ ) ; eye large, 3 in head, 1 in interorbital 

 space. D. 9 or 10 ; A. 11 or 12 ; V. 6 ; P. 14 ; B. 5 ; scales 25-10. Body 

 very deep, much compressed, much as in Cyprinodon ; caudal peduncle 

 very deep ; head depressed, rapidly tapering to a sharp, conical snout ; 

 the anterior profile somewhat concave ; females and young with the back 

 less elevated. Teeth very small, in a villiform band, those of the outer 

 series wide-set and considerably larger ; opercle adnate to shoulder girdle 

 above base of pectoral (as in Cyprinodon and Jordanella). Dorsal inserted 

 in advance of anal, its origin midway between caudal and middle of 

 eye, the longest rays in males reaching base of caudal, If in head ; anal 

 lower ; ventrals H in head. Intestinal canal as long as body. Male 



K If the genus Adinia is not recognized, this species should stand as Fundulus a-enicus.
